, the world was made up of a single continent through most of geologic
time. That continent eventually separated and drifted apart, forming
into the seven continents we have today. The first comprehensive theory
of continental drift was suggested by the German meteorologist Alfred Wegener
in 1912. The hypothesis asserts that the continents consist of lighter
rocks that rest on heavier crustal material—similar to the manner in
which icebergs float on water. Wegener contended that the relative
positions of the continents are not rigidly fixed but are slowly
moving—at a rate of about one yard per century.
Answer:
B
. Improvements in nutrition, sanitation, and health care cause death rates to fall in stage 2 of the demographic transition
Explanation:
- The epidemiologic transition occurs in medical geography and states that the changing population patterns in terms of fertility, life expectancy, and death can lead to causes of death.
- The second stage is viewed as the age of receding pandemics that states that due to the increase in medical aid and facilities. Morality progressively declines and the average life expectancy increases from 30 to 50 years.
Answer:
The time would be 2:00 pm.
Explanation:
This will work because 6 hours after 8:00 am would be 2:00 pm.
Earth is composed of four main layers, starting with an inner core at the planet's center, enveloped by the outer core, mantle, and crust. The inner core is a solid sphere made of iron and nickel metals about 759 miles (1,221 kilometers) in radius.
